The languages are: Dart, Julia, Clojure, Haxe, Fantom, OpenCL, Elixir, Go, Rust, Ceylon, and Harlan. What happened to these 11 programming languages? Have they become central to the development of open source software, have they stayed on the fringes, or are they only remembered like fingerprints on an abandoned handrail?
